Print a Nozzle Check
Result
When a printhead does not have any dropouts, it will look like the Nozzle Check
print of the black (K) section illustrated below.
Note: There is an indication of some poor directionality in one of the nozzles
illustrated in the top left section of the sample below, but it will not affect image
quality (although it could, if multiple adjacent nozzles show this problem).
